ctrl + space doensn't work on some websites (soundcloud for example) ... on most websites it works tho, so defenitely 4 stars !!!

feature request.

1.font size option.
The font size is too large. I would like to see more information in a small font size.

2.Instantly switch tabs whenever I select an item. At this time, after switching tabs, the Fast Tab Switcher window should remain open.
It's inconvenient to have to double-click an item to switch tabs.

3.Close icon at the end of each item.
It is much more intuitive and quicker than remembering to press the Ctrl+Delete button after selecting an item.
